SILC (Secure Internet Live Conferencing) is a protocol which provides secure conferencing services in the Internet. It can be used to send any kind of messages, in addition to normal text messages. This includes multimedia messages like images, video, and audio stream. All messages in the SILC network are encrypted and authenticated, and messages can also be digitally signed. SILC protocol supports AES, SHA-1, PKCS#1, PKCS#3, X.509, OpenPGP, and is being developed in the IETF. The software is delivered as SILC Client for end users, SILC Server for system administrators, and SILC Toolkit for application developers.
OpenIM is a Java implementation of a Jabber server. It is a complete rewrite of the Jaba Server project, and it supports the Jabber server to server communication protocol. It also supports Presence, Message, and Roster. Persistent storage is done in an XML file using XStream lib. It has been tested successfully with many clients such as Exodus, Rhymbox, GAIM, Psi, Greenthumb, and the Kopete.
Supybot is a clearly-written Python IRC framework and bot, intended to be both easily extensible and very flexible. Several modules are included by default. Numerous plugins are already written, including Google, Factoids, RSS, Quotes, and Relay. Plugins and their commands achieve greater utility via command nesting, something that no other IRC bot does. The user database is based on "capabilities" rather than obscure flags or arbitrary numeric "userlevels", giving the bot flexibility and fine-grained control (think ACLs vs. standard *nix permissions). Developing your own additions to the bot is simple with the base classes provided; writing a new command for the bot is as simple as writing a function. Unlike many other IRC frameworks, this simplicity is achieved at no cost to generality, which lets new programmers and old programmers alike feel at home in the framework.
JForum is complete, powerful, database-independent, and multi-threaded forum software. Features include unlimited forums and categories, topic watching, email notification, private messages, user ranking, an advanced permission schema, and moderation options. It provides support for many languages and customizable templates per user.

It features a StatServ, a SplitServ, flood protection, customized HTML output, a Jupe service, a channel search engine, and a number of drone/clone tracking tools. It fully supports many Hybrid 6 and 7 extensions.
CVSToys is a collection of companion tools for the Concurrent Versions System, better known as CVS. It currently contains FreshCVS, which performs actions in response to a commit. Actions include notification by various methods, updating a working copy, and rsync'ing to backup. Another key feature of FreshCVS notifications is that you receive one per commit, not one for each directory of the commit as loginfo-triggered scripts are prone to do. FreshCVS is extensible with Python, and notifications may be published by a Perspective Broker network service, allowing 3rd party clients to listen in.
Howie is an artificial intelligence agent with a natural language interface (a "chatterbot"). It is designed to be simple to install, configure, and extend. The emphasis is less on simulating a human conversation, and more on providing a "virtual assistant" which provides useful services to visitors through a natural, conversational interface.
